IdealPhotonics' 900-1000nm DBR diode, based on InGaAs/GaAs strained superlattice and sampling grating technology (±0.1nm accuracy), is a tunable laser achieving an ultra-wide 20nm tuning range and wavelength stability of ±0.008nm/℃. In cross-domain applications such as 980nm fiber amplification, 940nm laser medical applications, and 1030nm industrial processing, it simultaneously achieves a 55dB side-mode rejection ratio and 500mW output power. Its innovative "digital grating" architecture elevates tuning speed to the nanosecond level, setting a new industry standard for high-power near-infrared tunable light sources.Employing an InGaAs/GaAs strained superlattice and a digital sampling grating (±0.08nm accuracy), a breakthrough wavelength stability of ±0.006nm/℃ and a 22nm ultrawide tuning range are achieved. In three high-end applications—976nm fiber laser pumping (600mW output), 940nm surgical scalpel (tissue absorption coefficient optimized), and 1020nm industrial cutting—a 58dB side-mode rejection ratio and 0.01nm resolution are simultaneously achieved. Its innovative "electro-thermal dual-tuning" mechanism increases the wavelength switching speed to 500ns, redefining the performance limits of high-power tunable near-infrared lasers.
